Abstract
The utility model relates to a water disaster preventing system for an excavation working face, in particular to an excavation working face water disaster early warning system, which comprises a pressure sensor and flow rate sensors, wherein the pressure sensor is arranged on a water supply pipeline of a drill pipe, the flow rate sensors are arranged at water bursting point parts of an excavation working face bottom plate and an excavation working face standard water tank, the output end of the pressure sensor is connected with a mining signal processing substation through a CAN (controller area network) bus, the output ends of the flow rate sensors are connected with the mining signal processing substation through the CAN bus, and the mining signal processing substation is connected with a monitoring host for controlling a warning device through the CAN bus. The excavation working face water disaster early warning system can be used for comprehensively, systematically and effectively monitoring the water disaster of the excavation working face in real time, and the accident occurring probability is reduced.
Description
Technical field
The utility model relates to the prevention water damage system of driving face, is specially driving face system for pre-warning water disaster.
Background technology
In mine water inrush accident, occur in accounting for more than 80% of driving face, the protrusion-dispelling of driving face also just becomes the most important thing, and can prediction Pitwater disaster also becomes one of prerequisite ensureing Safety of Coal Mine Production.Current, the main method of driving face protrusion-dispelling is that physical detecting, chemical examination detect, bore detecting, wherein take bore detecting as main.And in bore detecting process, main abnormal by hydraulic pressure in drilling rod in its experience perception boring procedure and the process that discharges water with boring personnel, to having relatively high expectations of boring driver's quality and experience, the manometer being equipped with on the supply channel of boring is also only done the supervisory instrument of pressure of supply water, can not play prediction effect, therefore in bore detecting process, human factor is obvious, and water inrush accident easily occurs; Simultaneously the main emphasis of driving face hydrologic monitoring system is that mineral hydrological is observed and monitoring, and driving face shaft bottom water yield is strengthened and even a little less than the pre-alerting ability of gushing water situation, to the early warning in time of shaft bottom gushing water situation, and then causes shaft bottom water disaster; Thereby therefore go back at present neither one to driving face in real time, comprehensively, system, effectively monitor the monitoring system that reaches prediction effect.
Summary of the invention
The utility model can not carry out in real time driving face in order to solve the prevention water damage system of driving face, comprehensively, system, the effective problem of monitoring, driving face system for pre-warning water disaster is provided.
The utility model is to adopt following technical scheme to realize: driving face system for pre-warning water disaster, comprise pressure sensor and the flow transmitter that is arranged on driving face standard water tank and driving face base plate issue place on the supply channel that is arranged on drilling rod, the output of pressure sensor is processed substation (signal transmission and reception apparatus) by CAN bus and mining signal and is connected, the output of flow transmitter is processed substation by CAN bus and mining signal and is connected, and mining signal is processed substation and is connected with the monitoring host computer of controlling alarm by CAN bus.
In bore detecting process, the holed impact of hole depth and boring mud of drilling rod, in drilling rod, hydraulic pressure can change, according to liquid in airtight container during pressurized pressure raise and the constant transfer theory of pressure, in drilling rod, due to the impact of boring hole depth and boring mud, in drilling rod, hydraulic pressure increases, and in drilling rod, hydraulic pressure is passed to pressure sensor along water supply water route, pressure sensor is passed to mining signal by the data that record by CAN bus and processes substation, by mining signal, process substation again and be passed to monitoring exchange, when the hydraulic pressure numerical value of collection is greater than the safety value of setting in monitoring exchange, monitoring exchange is controlled alarm equipment alarm, can remind underground work personnel, this sample system is real-time by pressure sensor, effectively measure the hydraulic pressure in drilling rod supply channel, and reduce the human factor in bore detecting process, can reduce greatly the probability that water inrush accident occurs, the flow transmitter being arranged on driving face standard water tank is measured discharge, and arrives monitoring host computer by CAN bus transfer, the flow transmitter that is arranged on driving face base plate issue place is measured discharge, and arrives monitoring host computer by CAN bus transfer, monitoring host computer is by the discharge of flow transmitter transmission and the safety value comparison of setting, if the discharge of flow transmitter transmission is greater than the safety value of setting, it is the discharge variation abnormality in driving face standard water tank or driving face base plate issue place, monitoring host computer is controlled alarm equipment alarm, remind underground work personnel, withdraw in time or carry out safeguard procedures, avoiding causing water disaster.Therefore this driving face system for pre-warning water disaster can be in real time, comprehensively, system, effectively monitor the water damage of driving face, the probability of reduction accident generation.
This driving face system for pre-warning water disaster can be in real time, comprehensively, system, effectively monitor the water damage of driving face, reduce the probability that driving face accident occurs.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of pressure sensor.
Fig. 2 is the scheme of installation of flow transmitter.
The specific embodiment
Driving face system for pre-warning water disaster, comprise pressure sensor and the flow transmitter that is arranged on driving face standard water tank and driving face base plate issue place on the supply channel that is arranged on drilling rod, the output of pressure sensor is processed substation by CAN bus and mining signal and is connected, the output of flow transmitter is processed substation by CAN bus and mining signal and is connected, and mining signal is processed substation and is connected with the monitoring host computer of controlling alarm by CAN bus.During concrete enforcement, mine intrinsic safety electric source becomes alternating current after direct current, for mining signal is processed substation power supply.
